There are some places on the face of the earth that it is advised not to visit for your safety. We get acquainted with some of them in this report published by the American "Reader's Digest" magazine by Marisa Laliberty.

1- Snakes Island, Brazil

The island is home to an enormous group of the world's deadliest snakes, and the "golden spearhead" poison is so dangerous that it melts human flesh around the bite.

Some claim that there is a snake per square meter in certain areas. For safety reasons, the Brazilian government does not allow visitors to this island, and it is necessary to have a doctor on the next team to conduct research visits.

2- Qin Shi Huang Mausoleum, China

Farmers discovered the tomb of the first Chinese Emperor Qin Shi Huang in 1974, and archaeologists have since found about two thousand clay soldiers, and they expect that there are eight thousand others not discovered.

Despite the excavation, the Chinese government prevented archaeologists from touching the central tomb housing the body of Qin Shi Huang. The decision is partly due to respect for the dead, and also because of the fear that current technology is not eligible to carry out excavations without damaging ancient artifacts.

3- Chernobyl, Ukraine

On April 26, 1986, the explosion near Chernobyl, Ukraine, became the worst nuclear accident in history.

More than thirty years after the disaster, purging projects are still underway, and the director of the power plant believes that the area will not be habitable for at least twenty thousand years.

4- Region 51, Nevada

The United States government did not recognize the existence of Zone 51 until 1992, when documents issued in 2013 named the Nevada military base.

Officials have not yet revealed the type of research being conducted in this region, despite the claim of conspiracy theorists that there is a study of strange activity there.

The vast desert prevents any infiltration, and the area is very guarded, and even visitors who have security clearances enter the region 51 by private aircraft, and this method is one of many means that keep the area 51 very secret.

5- North Sentinel Island, India

The Andaman and Nicobar Islands are located in the Bay of Bengal, most of which are Indian lands. The Sentinelese tribe on the northern island of Sentinel is believed to have been around for sixty thousand years, and it is one of the last societies in the world that is still completely isolated from external societies.

In 2006, a boat of two fishermen drifted into the shallow waters of the northern island of Sentinel, but were killed by members of the tribe. Since then, there have been other reports of members of the tribe firing arrows on passing helicopters.

Since the Sentinels did not develop immunity to diseases that the rest of the population resisted, contact with strangers may be fatal for them. So the Indian government agreed to avoid any contact with them.

6- The Secret Vatican Archive

There are 53 miles of shelves that contain documents related to the Catholic Church, dating back to the eighth century located in a heavily protected area in the Vatican City.

Some of these documents include a letter in which Mary, Queen of Scotland, requests Pope Sixtus V to save her from execution. Researchers were allowed to enter the archive in 1881, but it is not easy to obtain an entry permit.

7- Fort Knox Castle in Kentucky

The coffers of Fort Knox Castle, home to most of the US gold reserves, are the most guarded location on the planet.

No one can enter the safe alone, and many codes are required to enter it, and many employees only know one code.

8- Svalbard vault for seeds

The Svalbard Seed Vault extends more than 320 feet in the middle of a mountain between Norway and the Arctic, and contains a huge collection of seeds in a vault designed to withstand man-made and natural disasters. And if a major catastrophe occurs, 890,000 seed samples preserved from nearly every country in the world will ensure diverse food choices for people. The cellar only opens a few times a year, and allows a limited number of applicants to enter to place the seeds in their shelves.

9- Lascaux Cave, France

Prehistoric paintings were found in the Lascaux Cave in 1940, and this cave became a tourist site after World War II. The carbon dioxide released by the visitors' breaths started destroying the cave paintings, which are now classified as a World Heritage Site by UNESCO, and as a result, the cave banned visitors in 1963, and only researchers and heritage protectors were allowed in.
